Be it known that I, EDWARD G. CARR, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Material- Transferring Apparatus, ot' which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates to material transferring apparatus and the object of the invention is to improve material transferring apparatus iii-the manner to be hereinafter described and claimed.

Referring to the drawings which accompany this specification and form a part hereof, which drawings illustrate an embodiment of this invention, and on which drawings the saine reference characters are used to designate the sameiparts wherever they inay appear on each of the several views, Figure l is an end elevation of a concrete mixer with the invention applied thereto; Fig. 2

is a view similar to Fig. 1 but showing parts in different positions; Fig. 3 is a side elevation; and Fig. 4 is a plan view. The con. crete mixer is illustrated schematically and all parts not necessary to a complete understanding of this invention are omitted from the drawings so far as practicable.

The present invention is an improvement on the material transferring apparatus for which I made application for Letters Patent on March 8, 1918, Serial Number 221,142.

Referring to the drawings, the reference numeral 1 designates a hopper which can be lifted to charge the mixing drum 2, or which can be lowered to be loaded or charged. A boiler' 3, engine l and cable 5 are illustrated as the power mechanism for lifting the hopper 1. When the cable 5 is slackened, the hopper' 1 will fall by its own weight and the weight of the hopper 1 is utilized to lift a receptacle containing material/to load or charge the hopper 1. 'lhe hopper 1, and the concrete mixer as a Whole are adapted to be moved from place to place and the object of the present invention is to combine an independently supported derrick with the hopper 1 in such a manner that the hopper' and derrick can be moved as a unit without any possibility of disturbing the relationship of the parts of the apparatus.

A derrick frame 7 is pivoted to the frame 8 of the concrete mixer in such a manner that it can move up or down with respect to thefi'ame of the concrete mixer but cannot move to any material extent either transversely or longitudinally thereof. Theeoncrete mixer illustrated is provided with. rear Wheels 9 and 10 and front wheelsA 11 and 12. The front wheels are secured upon an axle 13 which is movable withrespect to the frame 3 of the concrete mixer both on the king holt 1-1 and the rocking bolt 15. The rocking bolt 15 extends longitudinally of the frame 8 of the concrete mixer while the rear axle 1G extends transversely thereof so the rocking bolt 15 and the rear axle '16 afford convenient means for pivoting the derrick frame to the frame 8 of the concrete mixer in lines at right angles with each other.

The derrick frame 7 may be constructed in any suitable or preferred manner. As illustrated by the drawings, it is composed of an upright 17 a longitudinal tie member 18, a transverse tie member 19, a brace 20, a longitudinal, adjustable brace 21, an adjustable support 22, a mast 23 and a boom 21. The boom 24 is pivotally connected with the mast 23 and the mast is rotatably supported at its lower end by a step 25 secured to thenpright 17 and its upper end is rotatable within a strap 26 also secured to the. upright 17. The longitudinal, adjustable brace 21 is pivotally connected with the mast 23 and with the longitudinal tie member 18 and is composed of two parts connected by a turnbuckle 27. By turning theuturnbuckle 27, the upright 17'and mast 23 can be made vertical or inclined. The longitudinal tie member 18 is connected with the upright v17 by a bolt or pivot 28 to` permit of relative movement. The support 22 for the derrick 95 frame is illustrated as composed ot' two,

wheels 30 and 31, an axle 32 and an axle box ,l

The wheels 30 and 31 tread in the same i direction as the wheels of the concrete mixer so as to travel together and the upright 17 100 inost cases all adjustment that is necessary 1 06 will be the alining of the upright 17 with or away from thevertical by the turnbuckle 27 but, if necessary on account of grade or unevenness of the surface, the derrick frame itself may be raised or lowered to make the 110 l upright 17 and the'inast-23 wrtical. It is preferred to have the upright 17 and the mast 23 substantially vertical so 4there Will be n o tendency for the boom lto swing` but, if it is desii'ed to have the boom swing either toward or away from the hopper 1, the upright 17 (and theA mast 23) can be inclined from the vertical in a. manner which is Well understood. The transverse tie member 19 fits on the rocking bolt ,With rather a loose fit and the longitudinal tie member- 18 fits on the rear yaxle 16 With rather. a looset so that .there is iro-binding of the parts for the amount of relative movement required.

A flexible cable member 37 is fastened to the hopperl, passespver'pulleys 3S and 39, into hollovv upper :parti of the mast 23 and forms a boom tackle 40 for lifting they boom 24. The number of sheaves 41 and 42, and the number of turns of tlie cable 37, may be changed to obtain niorefoil less lift, of the boom 24 or less or moe lifting power. A clamp 43 Which automaticallygrips the boom AWhen subjected to strain provides simple means for lengthening and shortening` the reach of the cable 44. i

The derrick frame 7 is readily attached to or detached' fromthe concrete mixer. A

pin 45 prevents the rocking bolt 15 from being displaced and the removal of this pin permits the transverse tie member 19 to be slipped over'. the rocking bolt 15 or slipped off therefrom. Collars 4G and pins 47 keep the rear Wheels on the rear axle 16 and the removal of a pin and collar permits the longitudinal tie member 18 to be slipped over the end of the rear axle or slipped oil:z

therefrom. When the cable 37 is unfastened from the hopper 1 and the tie inembersv have been yremoved from the rocking bolt and rear axle, the derrick frame is entirely free from the concrete mixer.

It will be readily understood that when the hopper l is lifted to discharge its load or charge, the boom 24 and the receptacle 6 are lowered, and when the-hopper 'falls the boom 24 and a receptcale G are lifted so that the receptacle can be swinm around over the hopper and its contents-dumped into the hopper.

The construction illustrated and described permits the' Weight off-*the derrick .frame to be supported independently of the concrete mixer frame While-at all times, When moving the apparatus, for example, maintaining the vproper relation of the parts including the the hop-- per, an independently supported and adapted to lift a receptacle, when the hopper falls, to load or chargethe hopper.

2. The combination with a frame adapted to be moved from place toplace, of a hopper supported thereby, means for lifting the hopper, an independently supportedderrick frame movably connected with the hopper supportinof frame by connections at right angles to eachother, and means connected A\vith the hopper and extending to the derrick frame and adapted to lift a receptacle, when j 'the' hopper falls, to load or charge the hopper. l d 3. The combination With a frame adapted to be moved from place to place, of a hoppersupported thereby, means for liftinothe hopper,l an independently supported upright, longitudinal and transverse tie members movably connecting the upright withl the lhopper supporting frame, an adjustable l brace for the upright, a boom connected with the upright, and means connecting the hopper and boom to lift a receptacle, when the hopper falls, to load or charge the hopper. 4. The combination Witha concretemixei` provided With a hopper and means, for lifting the same, of an independently supported derrick frame movably connected With the concrete mixer, means for bodily adjusting the derrick frame vertically, and

means connected With the hopper and ex tending to the dei'rick frame and ladapted to lift a receptacle, when the hopper falls, to

load or charge the hopper.

In witness whereof I hereto aflix my signaturc.
